‘HD Ready’ is a Europe-wide standard designed to made HD technology less confusing. HD Ready TVs must have
• Minimum resolution of 720 horizontal lines (in widescreen format)
• Ability to display 720p and 1080i formats
• An HDMI or Digital Video Interface (DVI interface)
Full HD is a higher standard. Full HD TVs have screen resolutions of 1080p and can output at least 24 frames per second.
Full HD is becoming common, but you won’t see Full HD on normal TV channels for a long time, so it remains optional for many people.

Freeview is free digital terrestrial TV. FreeSat is a free digital satellite TV service, which gives you HD programming from people like the BBC without having to pay for a subscription to a service like Sky. You need a dish to receive Freesat but not Freeview.

Scart sockets are places where you can connect other devices to your TV. If you already have a DVD player, a VCR and a Playstation you might want to make sure your new TV has enough Scart interfaces so you don’t have to keep crawling round the back of the TV.
